Porosity is a very important factor in this model, the initial temperature (T\(_{ini}\) ) and the serpentinization time also strongly dependent on it. To estimate the porosity, we used the calculations from [1]} where they determine a size/pressure-dependent porosity for small icy bodies. The equation defined for the range Regime 3 (P \(>\)  2 MPa) was applied due to the pressure conditions in our objects:
\(\phi = a_{3}P^{b_3}\)
